Abstract

Translated fromFrench

Appareils radars mesurer la vitesse d'objets mobiles utilisant l'effet Doppler. Le mesureur de vitesse présente un boîtier 1 réalisé sous la forme d'un tronçon de tube en un matériau bon conducteur de la chaleur, à l'intérieur duquel sont disposés consécutivement et successivement une antenne 2, un bloc récepteur-émetteur 3 et un bloc 4 de traitement de l'information. L'antenne 2 et les blocs 3 et 4 sont reliés rigidement entre eux avec un contact thermique entre eux et avec le boîtier 1 et possèdent une configuration externe qui correspond à la forme de la surface interne du boîder 1. Application à la régulation du trafic routier.Radar devices measure the speed of moving objects using the Doppler effect. The speed meter has a housing 1 made in the form of a tube section of a material that is a good conductor of heat, inside which are arranged consecutively and successively an antenna 2, a receiver-transmitter unit 3 and a unit 4 information processing. The antenna 2 and the blocks 3 and 4 are rigidly connected to each other with thermal contact between them and with the housing 1 and have an external configuration which corresponds to the shape of the internal surface of the housing 1. Application to traffic regulation road.
